PingPing, PingPingSpecificSource, PingPingAnySource#
PingPing
, PingPingSpecificSource
, and PingPingAnySource
measure startup and throughput of single messages that are obstructed by
oncoming messages. To achieve this, two processes communicate with each
other using MPI_Isend/MPI_Recv/MPI_Wait
calls. The MPI_Isend
calls are issued simultaneously by both processes. For destination rank,
PingPingAnySource
uses the MPI_ANY_SOURCE
value, while
PingPing
and PingPingSpecificSource
use an explicit value.
